As an authorized dealer of genuine Chongqing Cummins Engine Company Limited (CCEC) engines, SinoMac is issuing an urgent global alert regarding a blatant counterfeiting case that has caused severe financial losses and irreversible brand damage. We expose the full chain of forgery, warn global equipment manufacturers and traders against price-only sourcing, and reaffirm our commitment to supplying only genuine, high-quality powertrain solutions.
Case Overview: A Clear Case of Engine Counterfeiting
Contract vs. Reality
Russian company ACMResource LLC purchased a CHETRA T40 bulldozer with a contract specifying a CCEC-manufactured QSK19C engine. Upon delivery, the engine nameplate clearly showed Chongqing San Chai Engine Company as the manufacturer – not Chongqing Cummins.

Forged “Proof Documents”
CHETRA provided two sets of papers claiming CCEC origin:
- A so-called Engine Test Report
- A Certificate of Origin from Chongqing Cumwonder Trading Co., Ltd.
Documentary Forgery Exposed
These papers are obvious fakes with blatant errors:
- The test report misspelled ENGINE TEST DATA LOG as L0G (letter “O” replaced with number “0”)
- No valid signatures or official stamps from CCEC
- The “Certificate of Origin” was issued by Chongqing Cumwonder Trading, which has no affiliation with Chongqing Cummins
- All supporting documents are unauthorized, self-fabricated, and unrelated to CCEC

Conclusion: This Is Deliberate Fraud
- The engine with serial number 56192105 is not a Chongqing Cummins product
- It is a Chongqing San Chai engine with forged documents pretending to be CCEC QSK19C
- This is typical counterfeit and shoddy equipment
Severe Consequences of Counterfeit Engines
- Direct financial losses for end users
- Catastrophic damage to CHETRA’s brand reputation
- ACMResource LLC has filed a lawsuit against CHETRA in local court
- Counterfeit engines undermine trust in genuine Chinese manufacturing and damage the global reputation of legitimate brands

Critical Warning: Never Sacrifice Quality for Low Price
To global equipment manufacturers, traders, and buyers: when sourcing engines from China, do NOT choose suppliers based only on price.
Low-cost offers often hide:
- Counterfeit cores
- Forged test reports
- Fake certificates
- Unqualified assembly
- Zero after-sales support

- Stable performance
- Long service life
- Valid warranty
